APPARATUS FOR EFFECTING THE TYING OF WOOL BALE AND LIKE TIES Filed July 25. 1932 2 Sheets-Sheet 2 Patented Mar. 13, 1934 UNITED STATES PATENT OFFICE APPARATUSFOR. EFFECTING THE TYING OF WOOL BALE AND LIKE TIES Application July 25, 1932, Serial No. 624,617 In Australia September 3, 1931 21 Claims.

This invention has reference to apparatus for effecting the tying of W001 bale and like ties and has been: devised to provide apparatus for engaging: a metallicv band with a shackle member in such a manner that when the tie is in position on a bale or: other package, the said tie will lock andtake the expansive strain of the bale without slippage.

The shackle for use with this apparatus is of 9 that type in. which a metal base has an opening provided by the formation of an integral tongue, the saidshackle forming the means whereby the ends of. a tie band will be-inseparably joined after passing about a bale or package which is under pressure for the purpose.

. It is'ana advantage to effect the anchorage of one end of the band to the shackle preparatory to placing theband about the bale and the apparatus to be hereinafter fully described is for that purpose, i. e. ofbending the band at one end about the tongue of the shackle and then returning the said end over the base of the shackle which may be removed with the attached band for disposal around a baleor other package.

The object of the invention is to provide apparatus having coacting tools, the operations of which are arranged in such order that a preliminary bending or folding of the tie band about a shackle tongue is performed by one tool and followed by a closing of the band end about the base and top of the shackle by the other tool, such tool cooperation being effected by the partial rotation of a. spindle operated by hand or by power.

An essential feature of the invention consists in arranging cams on the main spindle, said cams being set relative to the spindle in such a manner that the said. cams will impinge upon the actuating members of the tools to cause them to move in a direction governed by the curvature ofcam tracks,.to effect the. folding of the tie bands about the shackle tongue and top, means being pro vided to retain the shackle and band. in position during the folding operations while the said actuating members arespring loaded to return the tools to the normal position after the completion of their respective operations.

In order that the invention may be more readily understood, reference will now bemade to the accompanying drawings in which:--

Figure 11 is a plan of Figure 10.

Figure 12 is a detail view of one of the actuating members for operating the holding jaw.

According to this invention, the apparatus comprises an outer rectangular casing 5 having one side 6 detachable for the purposes of assembling the various integers therein, the said casing 5 being provided with base plates 7 for mounting the apparatus to any suitable supporting means.

Centrally disposed in the upper surface 8 of the casing 5 is a transverse recess 9 which is fitted at one side with spaced overlapping plates 12, the recess 9 at its longitudinal centre being formed with a right angled slot or recess 13 in front of which the shackle 14 is positioned in the transverse recess 9.

The shackle 14 is slipped into position in the transverse recess 9 with the extremities of its outer side 15 housed under the overlapping edges of the plates 12, the said recess 9 being stepped to provide a ledge 15a on which the shackle 14 seats, the tongue 16 thereof extending downwardly through the reduced portion 17 of the transverse recess 9.

To maintain the shackle 14 in the operative position illustrated in Figures 1 to 3, a spring controlled jaw 18 is adjustably mounted in the upper surface 8 of the casing so that the top 19 of the forward effective end of the jaw 18 engages with the inner side 21 of the shackle 14, the lower portion 22 of the jaw being extended below the shackle and formed at the end thereof with a downwardly inclined bevel 24, the purpose of which will be described.

The jaw 18 operates in a longitudinal slot 25 formed in the upper surface 8 of the casing in alignment with the recess 13 disposed on the other side of thetransverse shackle slot 9, the said jaw 18 being spring controlled as at 26 and operated by means of a short bent link 2'7 formed on theinner end of a transverse spindle 29, the centre of which is shaped with a lug or projection 30 positioned between a stationary vertical buffer 31 and a shoulder 32 on the rear end of the jaw, the spring 26 impinging on the buffer 31 with its other end connected to an integral stop member 32a formed on the jaw 13. g

The stationary buffer 31 is sweated or otherwise attached to a base plate 33 below which the said jaw is disposed and operates the said plate, being slotted as at 34 to permit the movement of the vertical stop member 3211.

The jaw 18 is illustrated in the operative position andwhen it is desired to remove the shackle after the completion of the band tying operation thereon, the link 27 is moved or partially rotated to cause the projection 30 to engage with the end shoulder 32 of the jaw which is thereby forced rearwardly under the influence of the spring 26, the setting of the link 27 maintaining the jaw in the outer released position whereby the shackle and attached band'may be removed from the transverse recess 9.

Disposed and operating within the casing 5 are right and left hand coacting tools 35 and 36 to attach a metal band to the shackle in the manner to be hereinafter described.

The right hand tool 35 is formed with a folding nose portion 37 which terminates in a shoulder 38, the surface of which is enlarged and curved to extend around to the stem 39 of the tool, the rear end of which is pivoted as at 40 to the upper end of a bell crank 41 pivotally mounted within the casing 5.

The nose 37 of the tool 35 is provided at each side with cheek plates 42 which overlap the shoulder surface 38 and. are correspondingly curved therewith, the lower portion of the curved cheek plates 42 being adapted to engage with and ride on a cam track 43 mounted within the casing 5 by means of the bracket 44 which is bolted to the rear wall 47 of the said casing as illustrated inFigure3.

The cheek plates 42 form a guideway for the end of the band to be delivered against the nose 37 of the tool 35 which, in its normal position is slightly rearward andbelow the tongue of the said shackle, with the cheek plates 42 in engage-- ment with the lower portion of the cam track 43 as illustrated in Figures 3 and '4.

The bell crank 41 is pivoted as at 43 to the rear wall 47 of the casing 5, the lower end of the bell the tool to'move forwardly and rise under the in-- fluence of the bell crank 41.

The coacting and finishing tool 36 is pivoted as at 54 to the upper end'of an actuating lever 55 which is pivoted as at 56 to the rear wall 47 of the casing, the lower end of the lever 55 having mounted thereon a roller 58 to engage with a cam 59 mounted on the main spindle 51 of the apparatus adjacent to the former cam 50 which actuates the right hand tool 35 as previously described.

The inner cam 59 is similarly shaped to the outer cam 50, but is oppositely disposed on the spindle 51 whereby on a partial rotation being imparted, the outer cam 50 operates its bell crank and consequently the right hand tool 35 prior to the inner cam 59 imparting movement to the actuating lever 55 and left hand tool 36.

The cam spindle 51 exteriorly of the casing 5 is fitted with a handle 60 for the purpose of operating the cams 50 and 59 and associated mechanism.

The actuating lever 55 is spring loaded as at 55a to ensure the quick return of the said lever and consequently the tool 36 after the completion of the operations thereof, the spring 55a being anchored between the lever 55 and the front wall 55?) of the casing 5 of the apparatus.

The left hand tool 36 is formed at its upper effective end in the manner of a rounded head 61 in which is fashioned a mouth portion 62, the sides of which are inclined towards each other from the front of the said mouth 62, the inclined sides uniting in curved base 63, the mouth 62 and head 61 engaging with and performing the final folding of the metal band on the shackle.

As illustrated in Figures 1 and 3, the head 61 of the left hand tool 36 is disposed inthe longitudinal slot or recess 13 in the upper surface 8 of the casing while the tool on its lower surface is bifurcated as'at 65 to receive a roller 66 in engagement with a cam track 6'7 formed on a bracket 63 bolted to the rear wall of the casing, the said cam track 67 being shaped with definite curve to define the movement of the left hand tool 36, which being independently pivoted to the actuating cam lever 55 is caused, by the roller 66 riding on the cam track 67, to move upwardly and then rearwardly, the reason for which will be described.

Figures 4, 5 and 6 illustrate in detail the respective operations of the right and left hand coacting tools 3.5 and 36 in attaching a metal band to the shackle 14 which is first placed in the central transverse slot 9 in position in front of the head 61 of the left hand tool as illustrated in Figures 2 and 3.

As illustrated in Figure 4, one end of the band a is delivered through the central slot or opening '70 of the shackle 14, the inclination of the shackle tongue 16 being such that the band is directed against the forward surface of the nose 37 of theright hand hool 35 and is then further extended into the chamielled space between the cheek plates 42 of the nose to terminate against the shoulder 33,- the positioniand shape of this tool 35 thereby governs the length of metal band a'to be inserted through the central opening 70 of the shackle 14. V

The spring controlled jaw 13 is then set in the operative position as illustrated to clamp the shackle 14 in position and incidentally the lower portion of the jaw impinges on the metal band a and forces same against the tongue 16 of the shackle whereby both shackle and band are retained in position by the jaw 18 during the operation of the respective tools 35 and 36.

With the inserted end b of the metal band a in engagement with the nose of the tool 35, the handle 60 is partially rotated to operate the outer cam 50 which, as previously described, actuates the said tool 35 which thereby moves forwardly and upwardly along the cam track 43 and carries with it the inserted end I) of the band, the path described by the said tool 35 being under and along the shackle 14 and tongue 16 thereof,

whereby the said end 5 of the band is folded around the end 16a of the shackle tongue and then passed along the underside of the shackle and tongue, the length of the inserted end b of the band being such that a projection portion 0 thereof is extended past the end of the shackle as illustrated in Figure 5 and with the band a partially folded and attached to the shackle 14, the tool has completed its operation and the shape of the cam is such that it then releases the pressure on the bell crank 41, whereby the spring 52 thereof returns same together with the tool 36 to their normal respective positions.

The relationship of the cams is such that a further partial rotation of the handle causes the inner cam 59 to operate the actuating lever 55, the left hand tool 36 then moves upwardly and rearwardly under the guidance of the cam track 67 and it is a particular feature of the invention that the projecting end portion 0 of the metal band a as positioned by the initial tool 35, is disposed in the path of the left hand tool 36, the rounded head 61 of which is brought intocontact with the projecting end c and bends or folds same upwardly against the front of the shackle 14 and then on the continued upward and rearward movement of the tool 36, the mouth 62 thereof engages with or closes on the now upturned end 0 of the band and folds same back over the upper surface of the shackle as illustrated more particularly in Figure 6.

It will be noticed that the lower side 62a of the mouth 62 of this latter tool 36 is slightly longer than its adjacent side, whereby, during the folding action, this lower side 62 impinges on the lower folded portion of the band and presses it against the underside of the shackle 14, while the upper side of the mouth folds the end of the said band back over the top of the said shackle as described and illustrated in Fig- The tool 36 has then completed its operation and the handle may be reversed to set the apparatus at normal, the shackle 14, together with the attached and folded band a being removed by releasing the jaw 18, in readiness for further operation of the apparatus.

Figure 6 illustrates the shackle 14 with the metal band a tied thereon, the coacting tools by the operations previously described folding the inserted end b of the band around and under the tongue of the shackle and then the projecting end 0 is folded back over the top of the shackle, thus providing a very effective lock or tie of the metal band on the shackle, which is inseparable therefrom during use, and tends to tighten rather than slip or free itself from the said band, the said shackle 14 with the end of the band anchored or attached thereon in the mamier described is then ready for transferring to a bale, the free end of the band being passed around the said bale and then inserted through the slot in the shackle to lie against the previously folded end of the band, thereby effecting a very efficient tie for the bale.

Figures 10 to 12 illustrate the means for op erating the retaining jaw 18 simultaneously and automatically with the handle 60 to eliminate the necessity for providing a separate adjustment of the jaw 18 as previously described and illustrated.

To effect the automatic functioning of the jaw 18 with the handle 60, the said jaw 18 is disposed within the casing 5 of the apparatus in its normal position and is slidalbly mounted on a ledge 75, the rear end 76 of the jaw being downturned and bifurcated as at 77 to receive the right-angled end 78 of a bent pivoted lever 79, said lever being pivoted as at 80, its lower end being adapted to engage with a lug 81 formed on a transverse spindle 82.

The spindle 82 extends through the front face of the casing 5 and on its outer extremity is fitted with a bifurcated or forked member 88, the bifurcated portion 84: thereof being adapted to engage at predetermined periods with a pin 85 attached to the inner side of the main handle 60.

The outer ends 86 of the bifurcated member 83 are rounded as illustrated in Figure 12 to permit of the ready entry of the handle pin 85 into the space between the bifurcations 84.

A spring 86 is disposed between the pivoted lever 79 and the rear wall of the casing 5 to assist the handle 66 in its operations.

With the automatic arrangement between the jaw 18 and the handle 60, the shackle and band are positioned in the transverse slot 9 as previously described, while the handle 60 is in the lower position illustrated in Figure l and as the said handle 60 is raised to operate the coacting tools 35 and 36, the pin 85 engages with the tool 83 and actually enters the bifurcated portion 84 which is thereby raised with the handle and imparts a partial rotation to the transverse spindle 82 whereby the lug 81 is brought into engagement with the lower end of the pivoted lever 79 causing same to thrust the jaw 18 forwardly to engage with the shackle as previously described.

The movement of the handle 60 is continued to complete the folding actions of the tools 35 and 36, and it will be obvious on the continued movement of the handle, its pin 85 engages from the bifurcated tool 88 and the lug 81 on the spindle 82 maintains the pivoted lever 79 and consequently the jaw 18 in their respective operative positions.

After the completion of the folding operations of the coacting tools, the handle 60 is returned and in its reverse movement the pin 85 again engages with the bifurcated tool 83 and returns same to its lower normal position and thereby frees the lug 81 of the spindle 82 from the pivoted lever 79 whereby the jaw 18 will slide back to its normal position under the action of the spring 86.

In this manner an independent setting of the jaw 18 is eliminated as same is performed by and during the operation of the handle 60 as described, the said jaw 18 being illustrated in the operative position in Figure 10, the various associated members being also illustrated in relation to the handle 60.

It will be understood that the cam spindle 51, in lieu of being controlled by the handle 60 may be suitably geared to a motor or other prime mover without departing from the ambit of the invention, and I do not wish to be arbitrarily confined to the particular shape and construction of the shackle, illustrated by way of example with the apparatus, but desire it to be understood that various improvements and modifications may be embodied without departing from the spirit and scope of the invention.
